LASSE BRENSDAL, OF PIERRE, SOUTH DAKOTA.

SHINGLE-BREAD MACHINE.

Application filed June 8, 1910, Serial No. 565,869.

To all whom it may concern Be it known that I, Lasso Bnnnsnan, a subjectof the King of Norway, residing at Pierre, in the county of Hughes andState of South Dakota, have invented certain new and useful Improvementsin Shingle- Bread Machines, of which the following is a specification.

The present invention relates to an improved machine for rolling doughor si1nilar plastic material into thin sheets, and is more particularlydesigned for the manufacture of what is commonly known as shingle breadand is termed in the Scandinavian language as flat bread, the saidshingle bread or flat bread being made by mixing flour, water, and otheringredients, into a dough, rolling the dough into a thin sheet aboutone-sixteenth of an inch thick, and then baking the same until itbecomes hard and crisp.

One of the objects of the invention is the provision of a machine ofthis character embodying novel features of construction whereby thedough can be easily and quickly rolled into a thin sheet, thereby savingthe uanufacturer from the hard work of rolling out the dough by handinto the small flat cakes in the usual manner.

The invention further contemplates a shingle bread machine which iscomparatively simple and inexpensive in its construction, which willoccupy a comparatively small amount of space when not in use, and whichwill operate in an effective manner to accomplish the desired result.

With these and other objects in view, the invention consists in certaincombinations and arrangements of the parts as will more fully appear asthe description proceeds, the novel features thereof being pointed outin the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in which:

Figure 1 is an end view of a shingle bread machine constructed inaccordance with the invention, portions being broken away. Fig. 2 is atop plan view of the same, portions being broken away. Fig. 3 is a sideview of the machine looking in the direction indicated by the arrows onFig. 1. Fig. 4: is a transverse sectional view on the line versesectional view through the upper Specification of Letters Patent.

roller. Fig. (i is an enlarged detail view of the lower end of one ofthe upright standards, the foot being removed and the clamp being shownas engaging a vertical support. Fig. 7 is a longitudinal sectional viewthrough the machine. Fig. 8 is an enlarged sectional view through thehopper, and Fig. 9 is a sectional view on the line 9-9 of Fig. 8.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Specifically describing the present embodiment of the invention, thesupporting frame of the machine comprises a pair of uprights 1 which areconnected at an intermediate point in their length by the cross bars 2,and are also connected at their upper ends by the cross bar 3, the saidcross bars serving to hold the uprights rigidly in a properly spacedposition. A roller i is journaled between the uprights 1 at a pointabove the cross bars 2, and the trunnions of this roller project throughthe uprights 1 and are provided with pinions 5. These pinions 5 meshwith similar pinions 6 applied to the ends of an upper roller 7 which isdesigned to cooperate with the before mentioned roller 1 to roll thedough into thin sheets. This upper roller 7 forms the bottom of a hopperA which is designed to receive a quantity of flour and to feed the sameto the top of the dough so that the said dough will not stick to theupper roller. The ends of the hopper A are in the nature of plates 8which fit against the inner faces of the uprights 1, the said platesbeing formed with outwardly projecting bearings 9 within which the upperroller 7 is journaled and which are loosely received within slots 10formed in the uprights. It will also be observed that the upper end ofeach of the plates 8 is formed with a block 11 which is slidably mountedwithin the upper portion of the corresponding slot 10, and which has aswiveled connection with the lower end of an adjusting screw 12, thesaid adjusting screw being threaded in the upper cross bar The lower endof each of the plates 8 extends below the hopper and is formed with aslot 13 loosely receiving the trunnions of the lower roller 4. It. willthus be obvious that the upper roller 7 is carried by the hopper A andthat both the said hopper and the upper roller can be raised and in theusual manner.

The side 11 of the hopper A is rigidly mounted and the lower edgethereof bears against one side of the upper roller 7. The opposite side15,however, is movably mounted so that the lower edge thereof can bemoved toward or away from the roller 7 to regulate the feeding of theflour from the hopper to the dough. This movable side 15 is shown asformed with inwardly eX- tending end flanges 15 which extend from thetop of the side to a point spaced from the bottom thereof, the lowerportion of each of the flanges being pivoted to the adjacent end plate 8as indicated at 16, while the upper port-ion of each of the flanges isformed with a transverse slot 17 adapted. to engage a clamping screw 18.Vith this construction it will be obvious that by loosening the clampingscrew 18 and swinging the movable side 15 of the hopper about the pivotpin 16, the space between the lower edge of the said movable side andthe upper roller 7 can be adjusted to regu late the flow of flourtherefrom.

The dough is designed to be fed to the rollers a and 7 from ahorizontally disposed shelf or table 19 which is applied to the uprights1 at a suitable elevation. In the present instance, this table 19 isshown as having an upwardly extending flange 20 at the sides and endthereof, the portions of the flange adjacent the uprights 1 beingextended upwardly and pivotally connected thereto at 21. hen the machineis not in use the table 19 can be swung upwardly about these pivots 21to admit of the machine being stored. in a very small amount of space.Some perforate member such as a screen 12 would be placed upon the table19 under the dough, and a supply of flour would be arranged under thisscreen 22. In this manner a proper amount would be automaticallysupplied to the lower surface of the dough as it was fed to the rollersto prevent the said dough from sticking to the lower roller 4.

The sheet of dough emerging from between the rollers 4: and 7 isreceived upon an end less apron 23 which passes around a roller 2&journaled in suitable bearings upon the uprights 1, and also around theroller 25 journaled in bearings 26 upon the outer ends of lateral arms27 projecting from the uprights 1. One end of the roller 24 is providedwit-h a pinion 28 which receives motion through an idler 29 from one ofthe pinions 5 applied to the lower roller 4. It will thus be obviousthat the apron 23 will be moved simultaneously with the rollers 4 and 7and will receive the thin sheet of dough as it emerges from the saidrollers. The bearings 26 are provided with plates 30 having slots 31therein which receive clamping screws 32. This construction admits ofthe roller 25 being properly adjusted to remove all slack from the apron23. A cutting block 33 which rests loosely upon the lateral arms 27 soas to be moved in and out as desired is arranged under the upper reachof the apron 23 so as to form a backing therefor and enable the dough tobe cut into the desired shapes by a blunt instrument while upon theapron. The lateral. arms 27 are preferably detachably applied to theuprights 1 so that they can be removed from the uprights and foldedagainst the same when the machine is not in use.

For the purpose of operating the machine a handle 34- is shown asapplied to one end of the lower roller f, the said. handle beingdesigned to be turned by the operator and motion being imparted throughthe. medium of the various pinions to both the upper roller 7 and theapron 23.

Shoes or cross pieces 35 are detachably applied to the lower ends of theuprights 1 and serve to hold the machine in an upright position when itis placed upon a table or other horizontal support. However, should itbe desired to apply the machine to the upper edge of a vertical supportthe shoes 35 would be removed and the clamps 36 which are applied to thelower ends of the uprights 1 brought into operation.

A bar 37 which connects the uprights 1 is arranged immediately below thelower roller 4: and has a scraper 38 secured thereto in some suitablemanner as by means of the screws 39. This scraper has a substantially Ushaped cross section and the edges thereof engage opposite sides of theroller 4 so as to effectively scrape the surface thereof and remove anyadhering particles therefrom.

In the operation of the device, dough will be placed upon the screen 22on the table 19 and will be fed from this table to the rollers 1 and 7the lower surface of the dough receiving flour through the screen 22 toprevent the dough from sticking to the lower roller, while the uppersurface of the dough receives flour from the hopper A to prevent thedough from sticking to the upper roller. These two rollers 4 and 7operate upon the dough as it passes between the same to produce a thinsheet which is delivered to the apron 23 upon which. it may be cut intothe desired shapes.

It is to be understood that when rolling thicker and heavier shinglebread, the upper roller 7 could be removed and replaced by a similarroller in which the grooves were somewhat deeper and spaced fartherapart. These grooves upon the upper roller may also be in any desiredconfiguration, either triangular as illustrated upon the drawings, orany other shape which may be found expedient.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is 2- 1. In a machine for rolling dough intosheets, the combination of a pair of spaced uprights, a fixed rollerextending between the uprights and provided at the ends there of withtrunnions which are journaled within the uprights, a hopper slidablymounted between the uprights and formed with an open bottom and alsowith ends which fit against the inner faces of the uprights, the saidends being extended downwardly below the hopper and having the lowerends thereof slotted to loosely receive the trunnions of the fixedroller, a second roller arranged within the open bottom of the hopperand journaled between the ends of the hopper, the said roller beingarranged parallel to the fixed roller, and means for sliding the hopperbetween the uprights to vary the distance between the rollers, the slotsin the downwardly extended ends of the hop per cooperating with thetrunnions of the fixed roller to hold the hopper against lateraldisplacement.

2. In a machine for rolling dough into sheets, the combination of a pairof spaced uprights formed with slots, at cross bar connecting the upperends of the uprights, a fixed roller extending between the uprights andprovided at the ends thereof with trunnions which are journaled betweenthe uprights, a hopper formed with an open bottom and slidably mountedbetween the uprights, the ends of the hopper bearing against the innerfaces of the uprights and extending downwardly below the bottom of thehopper where they are slotted to loosely receive the trunnions of thefixed roller, a bearing block projecting outwardly from each end of thehopper and loosely received within the slot of the respective upright, asecond block projecting outwardly from each end of the hopper and alsoreceived within the slot of the respective upright, a movable rollerjournaled between the first mentioned blocks and arranged within theopen bottom of the hopper parallel to the first mentioned roller, andadjustingscrews threaded upon the cross bar and engaging the secondmentioned blocks for sliding the hopper to regulate the distance betweenthe rollers, the hopper being directed in its movements by the blockswhich are received within the slots of the uprights, and also by theslotted ends of the hopper which receive the trunnions of the firstmentioned roller.

In testimony whereof I aflix my signature in presence of two witnesses.

LASSE BRENSDAL.
